Description
Technical Field

Background
In the actual production and processing process of electrochemical machining, electrolyte plasma polishing, electroplating, micro-arc oxidation and other electric processing technologies, due to the continuity of processing and production, the change of the component parameters of the used electric processing solution needs to be monitored in real time, and once deviation occurs, adjustment is immediately made, so that the production process is stable and controllable, and the processing quality of products is ensured. On the other hand, in the scientific research process of scientific research experiments by using the processing technology, scientific research institutions such as colleges and universities need to detect the parameter change of the electrochemical machining solution in real time so as to know which factor in the electrochemical machining solution affects the quality of the machined surface or which factor among different factors affects the quality of the machined surface more, so that the mechanism of the machining process is researched, and theoretical guidance basis is provided for actual machining production.
In the electrochemical machining, electrolyte plasma polishing, micro-arc oxidation and electroplating and other electrical machining technologies, an electrical machining solution is in an electrified state in a machining process, and parameters of the electrical machining solution to be detected usually comprise parameters such as pH, conductivity, ion concentration of a formula solution and metal ion concentration of a working machine, but due to the working principle of the detection instrument, the detection instrument for the parameters cannot detect the solution in the electrified state (the electrical machining solution passes through current in the solution). If the detection is directly carried out in the solution under the electrifying working condition by force, the measured data result is not accurate, and the detection instrument is damaged. In addition, the current online ion concentration detector generally requires that the temperature of the detected solution is below 50-60 ℃, so that the detection cannot be carried out under the high-temperature electrochemical machining solution (generally 80-95 ℃) of electrolyte plasma polishing.
In addition, after the processing by the technology, waste liquid containing heavy metals is generated, and can be discharged after reaching the national discharge standard after being treated by a corresponding waste liquid treatment method such as a chemical method, a physical treatment method, a biological treatment method and the like. However, in the waste liquid treatment process, how to judge whether the parameters of the water data such as PH, metal ion concentration and the like reach the standard is an important problem. At present, whether the treated waste liquid reaches the standard is mainly judged by adopting an empirical formula, namely, the heavy metal content in the waste liquid is firstly detected, the optimal treatment process parameters for reaching the standard of the waste liquid discharge are obtained in a simulation manner in a laboratory, and then the optimal treatment process parameters are popularized to production application. In addition, the waste liquid effluent data can be detected by adopting an off-line detection mode, but the problems of inconvenient detection, detection value hysteresis, incapability of detecting the waste liquid effluent data in real time and the like exist.
In view of the above, there is a need for a solution real-time detection device for integrated electrical processing and post-electrical processing waste liquid treatment devices, which can detect both the solution in the power-on state during the electrical processing and the effluent data of the processed waste liquid in real time.
